FOUNTAIN-PEN.

- SPECIFICATION forming part of Letters Patent No. 538,499, dated April30, 1895.

Application filed March 19, 1894. Serial No. 504,126. (No mo'deLl i Toall whom t may concern.-

Be it known that I, GEORGE WILLIAM BRY- DEN, of Boston, in the county ofSuffolk and State of Massachusetts, have invented'certain new and usefulImprovements in Fountain- Pens, of which the following is aspecification.

This invention relates to an improvement in fountain pens, the principalobject being to simplify the construction of a pen of this characterwithout detracting from its efficiency.

To the above end the invention may be said to consist in certain novelfeatures of construction and combinations of parts recited in the claimsappended and speciticall y described in the specication which lfollows.

The accompanying drawings form part of the specification, and theyillustrate an embodiment of the invention.

Figure 1 shows a longitudinal section of the pen. Fig. 2 showsacross-section on line 2 2 of Fig 1. Fig. 3 shows the pen-point andtongue in the flat. Fig. 4 shows a longitudinal sec'- tion of the penpoint and tongue. Fig. 5

shows a pen-point embodying the inventionv fitted to a hollow holder,such as commonly used with an ordina-ry dip-pen. Fig. 6 shows asectional view of a modified form of penpoint fitted to a holder. Fig. 7shows a plan view of this modified form of pen-point in the flat. Fig. 8shows a longitudinal section of the pen-point detached. Fig. 9 shows aside edge View of the same completed.

The body of the pen constituting the reservoir may be made in one ormore parts. It is shown in Figs. 1 and 2 as made in two parts, a, and b,the latter screwing into the former and itself being fitted with ascrew-threaded lug, c.

To fill the reservoir the member,b, is screwed out and the member, a.,charged and then the part, b, is replaced. The screw-plug, c, isflattened on one side, as shown at c in Fig. 2, and is split as iscommon in plugs of this kind to adapt it for securely holding in thepenpoint. The latter comprises a part, d, of shape and form of anordinary pen-point, with a divided nib and an enlarged opening, d', atthe base ofv the dividing split; and a tongue, d2, connected with thepart, d, by a reduced neck, d3. These parts are preferably all formed inone piece, as shown, and the tongue, d2, extends along the under-side ofthe part, d,

,e in Fig.

to a point between the extremity thereof and the opening, d', the neck,clbeing nent around to thus dispose the tongue.

When'the parts of the pen are assembled the flat tongue, d2, liesagainst the flattened side, c', of the plug, c, the part, CZ, liesagainst the inner wall of the body member, b, and the doubled neck, d3,projects into the reservoir. A duct or passage, e, exists between thetongue, d2, and the pen-point, d, and in action, air enters the opening,d', in the pen, d, and fiows up this passage, and the ink feeds to thepen in fine streams along the edges of the tongue at each side ofthepassage, e, as indicated at Thus a single passage serves both as anair-duct and an ink-duct.

By reason of the feed taking place in fine streams along the edges ofthe tongue, blotting of the pen as the supply of ink in its reservoirgives out, is effectually guarded against. Should a solid column of inkflow down the passage, e, such as might form a blot, this column closesthe air-duct and the ink is arrested before a blot can be made.

A. pen-point of the construction shown may be employed with a hollowholder such as cornmonly employed with an ordinary dip-pen, and such anarticle thus converted into a fou ntain-pen.

In Fig. 5 the letter,f, designates a hollow pen-holder of the well-knownform, and,f,

the split-plug which screws into the holder, and secures thepen-point,f2, which is of the same form as before described, its innerend projecting into the holder. The latter may be readily filled withwriting fluid by removing the plug, f. The action is the same asdescribedwith reference to the two-part holder.

In the modified form shown in Figs. 6, 7, 8, and 9, the pen-point, g, isformed at its base on either side of the neck, g', with points, g2,

designed to bear against the wall of the reservoir, h. (See Fig. 6.) Theobject of this provision is to prevent gumming of ink remaining in thepen-point when the penis not in use, the said points, g2, inducing theflowing of ink back into the reservoir when the pen is inverted. Thefeeding tongue, g3, is formed beyond the neck, g', as before.

Having thus explained the nature of the invention and described a way ofconstructing and using the same, though without at- ICO tempting to setforth all of the forms in which it may be made or all of the modes ofits use, it is declared that what is claimed isl. A pen-point forfountain pens comprising a body portion of the usual form beingsubstantially semi-circular in cross-section and pointed and split atone end to'forin nibs with an opening at the base of the split; a narrowneck extending back from the middle of the base of the body-portion andbent back under itself; and a tongue extending from the neck along theinner side of the body-portion as far as the opening at the base of thenibs, said tongue being partially inclosed by the body-portion whereby aduct is formed for the ink to flow through from its point of entrance atthe sides of the bent-over neck to the opening at the base of the nibs.

2. A fountain pen .comprising in its construction a body constituting areservoir, a plug in one end of said body and flattened ou one side, anda pen-point and tongue formed in one piece, the tongue extending alongthe inner side of the pen-point, and the two inserted between the plugand the wall of the body and extending into the reservoir.
